What's the preprocess function for targeting the home page in my Drupal 8?

Edit:

Ok, here's what I'm trying to do. I want to apply a javascript to the front page of my site only. Here's what I'm trying:

function mytheme_preprocess_page(&$variables) {
  if ($variables[‘is_front’]) {
    $variables[‘#attached’][‘library’][] = ‘mytheme/home_page_jquery’;
  }
}

The $variables['#attached'] line doesn't seem to work as it keeps giving me the website encountered an unexpected error error.

I got the idea to use this non-working code from https://www.drupal.org/node/2216195.

  • The home/front page is now a page view called Frontpage with url/path of /node so you may have to give more details on what you're trying to achieve with the preprocess. – No Sssweat Aug 17 '16 at 8:44

    Thanks for your comment I added what I'm trying to accomplish. Should have just done so from the beginning. – Sage Aug 17 '16 at 18:28
  • PHP doesn't use and as string delimiters. You are using the wrong string delimiter in $variables[‘is_front’] and the next line. – kiamlaluno Aug 17 '16 at 18:32
  • good grief, I see what you mean. thanks for pointing out the obvious! – Sage Aug 17 '16 at 18:48

To target the front page in a preprocess function you need a condition, because for preprocess you can't use name suggestions:

function mytheme_preprocess_page(&$variables) {
  if ($variables['is_front']) {
    // your code
  }
}

What you call home page, for Drupal is the front page. The suggestion given by system_theme_suggestions_page() for the front page is page__front; similarly, system_theme_suggestions_html() suggests html__front. There aren't other suggestions.

If by home page you mean a page that is not the front page, you need to implement your own hook_theme_suggestions_HOOK().
